Late video-assisted thoracoscopic surgery versus thoracostomy tube reinsertion for retained hemothorax after penetrating trauma, a prospective randomized control study.

BACKGROUND: Early video-assisted thoracoscopic surgery (VATS) is the recommended treatment of choice for retained hemothorax (RH). A prospective single-center randomized control study was conducted to compare outcomes between VATS and thoracostomy tube (TT) reinsertion for patients with RH after penetrating trauma in a resource constrained unit. Our hypothesis was that patients with a RH receiving VATS instead of TT reinsertion would have a shorter hospital stay and lesser complications. MATERIALS AND METHODS: From January 2014 to November 2019, stable patients with thoracic penetrating trauma complicated with retained hemothoraces were randomized to either VATS or TT reinsertion. The outcomes were length of hospital stay (LOS) and complications. RESULTS: Out of the 77 patients assessed for eligibility, 65 patients were randomized and 62 analyzed: 30 in the VATS arm and 32 in the TT reinsertion arm. Demographics and mechanisms of injury were comparable between the two arms. Length of hospital stay was: preprocedure: VATS 6.8 (+/-2.8) days and TT 6.6 (+/- 2.4) days (p = 0.932) and postprocedure: VATS 5.1 (+/-2.3) days, TT 7.1 (+/-6.3) days (p = 0.459), total LOS VATS 12 (+/- 3.9) days, and TT 14.4 (+/-7) days (p = 0.224). The TT arm had 15 complications compared to the VATS arm of four (p = 0.004). There were two additional procedures in the VATS arm and 10 in the TT arm (p = 0.014). CONCLUSION: VATS proved to be the better treatment modality for RH with fewer complications and less need of additional procedures, while the LOS between the two groups was not statistically different.

Intracapsular neck of femur fractures secondary to civilian gunshot injuries: an inter- and intra-observer agreement study on classification and treatment using the AO/OTA classification.

PURPOSE: Numerous classification systems have been developed for neck of femur fractures, but none have been tested for reliability in gunshot injuries. Our primary objective was to assess the inter-observer and intra-observer reliability of the AO/OTA classification system when applied to intracapsular neck of femur fractures secondary to low-velocity civilian gunshots wounds (GSWs). Our secondary objective was to test the reliability of the AO/OTA classification system in guiding surgeon treatment choices for these fractures. PATIENTS AND METHODS: Eighteen reviewers (six orthopaedic traumatologists, six general orthopaedic surgeons and six junior orthopaedic fellows) were given a set of 25 plain radiographs and CT scans of femur neck fractures secondary to GSW. For each clinical case, all reviewers selected a classification as well as treatment option from a list of given options. Inter-observer reliability was measured at the initial classification. The exercise was repeated 10-12 weeks later by the same 18 reviewers to test intra-observer reliability. RESULTS: The Fleiss kappa values indicate only slight agreement amongst raters, across all experience levels, for both injury classification and treatment. Intra-observer agreement was fair across all experience levels for both injury classification and treatment. CONCLUSION: The AO/OTA classification showed only slight reliability in classification of gunshot fractures of the femur neck. With only fair reliability, it also failed to guide surgical treatment thus rendering its routine use in daily clinical practice of questionable value.

A Prospective Audit of 805 Consecutive Patients With Penetrating Abdominal Trauma: Evolving Beyond Injury Mechanism Dictating Management.

BACKGROUND: Global trends of penetrating abdominal trauma (PAT) have seen a shift toward a selectively conservative management strategy. However, its widespread adoption for gunshot injuries has been sluggish. The purpose of this study is to compare the injury mechanisms of gunshot (GSW) and stab wounds (SW) to the abdomen in presentation, management, and outcomes. METHODS: Prospective cohort study, set in Cape Town, South Africa, over 2 years. All patients presenting to the center with PAT during this time were included. Presentation, management, and outcomes were compared by injury mechanism, with a focus on the operative strategy (operative vs nonoperative). RESULTS: During the study period, 805 patients (SW 37.6%; GSW 62.4%) with PAT were managed. Immediate laparotomies were performed in 119 (39.3%) SW and 355 (70.7%) GSW, with a therapeutic laparotomy rate of 85.7% and 91.8% for SW and GSW, respectively. Nonoperative management (NOM) was implemented in 184 SW (60.7%) and 147 GSW (29.3%) (P < 0.001), with a 92.9% and 92.5% success rate for SW and GSW, respectively. The therapeutic laparotomy rate for the delayed laparotomies (DOM) was 69.2% for SW, and 90.9% for GSW. The accuracy of clinical assessment (with adjuncts) in determining the need for laparotomy was: GSW-92% and SW-91%. Univariate analysis revealed the mechanism not to be associated with DOM. The overall mortality rate was 7.2%, and nonfatal morbidities 22.2%. CONCLUSION: Although GSW is a more morbid and often fatal injury, the general principles of selective conservatism hold true for both GSW and SW, equally.

An Update on Foley Catheter Balloon Tamponade for Penetrating Neck Injuries.

BACKGROUND: Foley catheter balloon tamponade (FCBT) for bleeding penetrating neck injuries (PNIs) is effective. This study aims to audit the technique and outcomes of FCBT. METHODS: Adult patients with PNIs requiring FCBT presenting to Groote Schuur Hospital (GSH) within a 22-month study period were prospectively captured on an approved electronic registry. Retrospective analysis included demographics, major injuries, investigations, management and outcomes. RESULTS: During the study period, 628 patients with PNI were treated at GSH. In 95 patients (15.2%), FCBT was utilised. The majority were men (98%) with an average age of 27.9 years. Most injuries were caused by stab wounds (90.5%). The majority of catheters (81.1%) were inserted prior to arrival at GSH. Computerised tomographic angiography (CTA) was done in 92.6% of patients, while eight patients (8.4%) required catheter-directed angiography. Six were performed for interventional endovascular management. Thirty-four arterial injuries were identified in 29 patients. Ongoing bleeding was noted in three patients, equating to a 97% success rate for haemorrhage control. Thirteen (13.7%) patients required neck exploration. Seventy-two (75.8%) patients without major arterial injury had removal of the catheter at 48-72 h. Two of these bled on catheter removal. A total of 36 complications were documented in 28 patients (29.5%). There was one death due to uncontrolled haemorrhage from the neck wound. CONCLUSION: This large series highlights the ease of use of FCBT with high rates of success at haemorrhage control (97%). Venous injuries and minor arterial injuries are definitively managed with this technique.

The Effect of Human-Immunodeficiency Virus Status on Outcomes in Penetrating Abdominal Trauma: An Interim Analysis.

BACKGROUND: The purpose of this study was to determine whether the outcomes of hemodynamically stable patients undergoing exploratory laparotomy for penetrating abdominal trauma differed as a result of their HIV status. METHODS: This was an observational, prospective study from February 2016 to May 2017. All hemodynamically stable patients with penetrating abdominal trauma requiring a laparotomy were included. The mechanism of injury, the HIV status, age, the penetrating abdominal trauma index (PATI), and the revised trauma score (RTS) were entered into a binary logistic regression model. Outcome parameters were in-hospital death, morbidity, admission to intensive care unit (ICU), relaparotomy within 30 days, and length of stay longer than 30 days. RESULTS: A total of 209 patients, 94% male, with a mean age of 29 ± 10 years were analysed. Twenty-eight patients (13%) were HIV positive. The two groups were comparable. Ten (4.8%) laparotomies were negative. There were two (0.96%) deaths, both in the HIV negative group. The complication rate was 34% (n = 72). Twenty-nine patients (14%) were admitted to the ICU. A higher PATI, older age, and a lower RTS were significant risk factors for ICU admission. After 30 days, 12 patients (5.7%) were still in hospital. Twenty-four patients (11%) underwent a second laparotomy. The PATI score was the single independent predictor for complications, relaparotomy, and hospital stay longer than 30 days. CONCLUSIONS: Preliminary results reveal that HIV status does not influence outcomes in patients with penetrating abdominal trauma.

Development and validation of a pancreatic injury mortality score (PIMS) based on 473 consecutive patients treated at a level 1 trauma center.

BACKGROUND: This study sought to develop a pancreatic injury mortality score (PIMS) to identify patients at greatest risk of in-hospital mortality after a major pancreatic injury. METHODS: The study used data from a prospective database of 473 patients treated for pancreatic injuries between January 1990 and December 2015. Two thirds of the patients were assigned to the derivation cohort and one third to the validation cohort. Clinical correlates of in-hospital death were identified and considered in stepwise logistic regression analyses that identified the factors included in the risk index. RESULTS: Five variables, age >55, shock on admission, a vascular injury, number of associated injuries and American Association for the Study of Trauma (AAST) pancreatic injury scale correlated with in-hospital death and were used to calculate PIMS. The final score ROC in the derivation dataset was 0.84 (95% CI 0.79-0.89) and in the validation dataset was 0.91 (95% CI 0.84-0.97), which were comparable (p = 0.1). Finally, cut-off scores were used to generate three risk groups and the rate of mortality within the low (PIMS 0-4), medium (PIMS 5-9), and high risk (PIMS 10-20) groups were not significantly different. The scoring system was tested in a validation cohort and showed good calibration and discrimination for in-hospital mortality. CONCLUSIONS: We have derived and validated the PIMS, a novel organ-specific risk prediction score calculated from five variables for in-hospital mortality following major pancreatic trauma. PIMS is simple, quick and easily understandable, increases clinical risk prediction for patients with complex pancreatic and can be used as a benchmark for survival.

Indications for Use of Damage Control Surgery in Civilian Trauma Patients: A Content Analysis and Expert Appropriateness Rating Study.

OBJECTIVES: To characterize and evaluate indications for use of damage control (DC) surgery in civilian trauma patients. BACKGROUND: Although DC surgery may improve survival in select, severely injured patients, the procedure is associated with significant morbidity, suggesting that it should be used only when appropriately indicated. METHODS: Two investigators used an abbreviated grounded theory method to synthesize indications for DC surgery reported in peer-reviewed articles between 1983 and 2014 into a reduced number of named, content-characteristic codes representing unique indications. An international panel of trauma surgery experts (n = 9) then rated the appropriateness (expected benefit-to-harm ratio) of the coded indications for use in surgical practice. RESULTS: The 1107 indications identified in the literature were synthesized into 123 unique pre- (n = 36) and intraoperative (n = 87) indications. The panel assessed 101 (82.1%) of these indications to be appropriate. The indications most commonly reported and assessed to be appropriate included pre- and intraoperative hypothermia (median temperature <34°C), acidosis (median pH <7.2), and/or coagulopathy. Others included 5 different injury patterns, inability to control bleeding by conventional methods, administration of a large volume of packed red blood cells (median >10 units), inability to close the abdominal wall without tension, development of abdominal compartment syndrome during attempted abdominal wall closure, and need to reassess extent of bowel viability. CONCLUSIONS: This study identified a comprehensive list of candidate indications for use of DC surgery. These indications provide a practical foundation to guide surgical practice while studies are conducted to evaluate their impact on patient care and outcomes.

Mobile health technology transforms injury severity scoring in South Africa.

BACKGROUND: The burden of data collection associated with injury severity scoring has limited its application in areas of the world with the highest incidence of trauma. MATERIAL AND METHODS: Since January 2014, electronic records (electronic Trauma Health Records [eTHRs]) replaced all handwritten records at the Groote Schuur Hospital Trauma Unit in South Africa. Data fields required for Glasgow Coma Scale, Revised Trauma Score, Kampala Trauma Score, Injury Severity Score (ISS), and Trauma Score-Injury Severity Score calculations are now prospectively collected. Fifteen months after implementation of eTHR, the injury severity scores were compared as predictors of mortality on three accounts: (1) ability to discriminate (area under receiver operating curve, ROC); (2) ability to calibrate (observed versus expected ratio, O/E); and (3) feasibility of data collection (rate of missing data). RESULTS: A total of 7460 admissions were recorded by eTHR from April 1, 2014 to July 7, 2015, including 770 severely injured patients (ISS > 15) and 950 operations. The mean age was 33.3 y (range 13-94), 77.6% were male, and the mechanism of injury was penetrating in 39.3% of cases. The cohort experienced a mortality rate of 2.5%. Patient reserve predictors required by the scores were 98.7% complete, physiological injury predictors were 95.1% complete, and anatomic injury predictors were 86.9% complete. The discrimination and calibration of Trauma Score-Injury Severity Score was superior for all admissions (ROC 0.9591 and O/E 1.01) and operatively managed patients (ROC 0.8427 and O/E 0.79). In the severely injured cohort, the discriminatory ability of Revised Trauma Score was superior (ROC 0.8315), but no score provided adequate calibration. CONCLUSIONS: Emerging mobile health technology enables reliable and sustainable injury severity scoring in a high-volume trauma center in South Africa.

An Objective Assessment of the Surgical Trainee in an Urban Trauma Unit in South Africa: A Pilot Study.

BACKGROUND: Surgical outcomes are provider specific. This prospective audit describes the surgical activity of five general surgery residents on their trauma surgery rotation. It was hypothesized that the operating surgical trainee is an independent risk factor for adverse outcomes following major trauma. MATERIALS AND METHODS: This is a prospective cohort study. All patients admitted, over a 6-month period (August 2014-January 2015), following trauma requiring a major operation performed by a surgical trainee at Groote Schuur Hospital's trauma unit in South Africa were included. Multiple logistic regression models were built to compare risk-adjusted surgical outcomes between trainees. The primary outcome measure was major in-hospital complications. RESULTS: A total of 320 major operations involving 341 procedures were included. The mean age was 28.49 years (range 13-64), 97.2 % were male with a median ISS of 9 (IQR 1-41). Mechanism of injury was penetrating in 93.42 % of cases of which 51.86 % were gunshot injuries. Surgeon A consistently had the lowest risk-adjusted outcomes and was used as the reference for all outcomes in the regression models. Surgeon B, D, and E had statistically significant higher rates of major in-hospital complications than Surgeon A and C, after adjusting for multiple confounders. The final model used to calculate the risk estimates for the primary outcome had a ROC of 0.8649. CONCLUSION: Risk-adjusted surgical outcomes vary by operating surgical trainee. The analysis thereof can add value to the objective assessment of a surgical trainee.

Selective nonoperative management in 1106 patients with abdominal gunshot wounds: conclusions on safety, efficacy, and the role of selective CT imaging in a prospective single-center study.

OBJECTIVE: The primary aim of this study was to delineate the role of computed tomography (CT) in patients undergoing NOM for AGSW. BACKGROUND: Nonoperative management (NOM) of abdominal gunshot wounds (AGSWs) remains controversial. METHODS: This prospective study included all patients with abdominal gunshot injuries admitted to our trauma center from April 1, 2004 to September 30, 2009. Exclusion criteria included patients with peritonitis, hemodynamic instability, unreliable physical examination, head and spinal cord injury with an AGSW underwent immediate laparotomy. The remaining patients were selected for NOM. Nonperitonitic stable patients with right-sided thoracoabdominal/right upper quadrant gunshots and/or hematuria underwent mandatory CT with intravenous contrast. CT to detect missile trajectory was optional. The primary outcome measure was failure of NOM. Secondary outcomes were unnecessary laparotomy rates and mortality. RESULTS: A total of 1106 patients with abdominal gunshot injuries were admitted. Of these, 834 (75.4%) underwent immediate laparotomy, whereas 272 (24.6%) were selected for NOM. In the former group, there were 56 (6.7%) deaths and 29 (3.5%) unnecessary laparotomies, whereas in the latter NOM group, 82 (30.1%) patients were managed by serial clinical examination alone, whereas 190 (69.9%) patients underwent abdominal CT scanning, in addition to serial clinical examination. The overall NOM success rate was 95.2%. Of the 13 patients undergoing delayed laparotomy, there were 10 therapeutic, 2 nontherapeutic, and 1 negative laparotomy. CONCLUSIONS: The NOM of appropriately selected patients with AGSW with selective use of CT scanning is feasible, safe, and effective, but largely based on findings from serial clinical examinations.

Screening for occult penetrating cardiac injuries.

OBJECTIVE: To determine the sensitivity of emergency department ultrasonography (US) in the diagnosis of occult cardiac injuries. BACKGROUND: Internationally, US has become the investigation of choice in screening patients for a possible cardiac injury after penetrating chest trauma by detecting blood in the pericardial sac. METHODS: Patients presenting with a penetrating chest wound and a possible cardiac injury to the Groote Schuur Hospital Trauma Centre between October 2001 and February 2009 were prospectively evaluated. All patients were hemodynamically stable, had no indication for emergency surgery, and had an US scan followed by subxiphoid pericardial window exploration. RESULTS: There were a total of 172 patients (median age = 26 years; range, 11-65 years). The mechanism of injury was stab wounds in 166 (96%) and gunshot wounds in 6. The sensitivity of US in detecting hemopericardium was 86.7%, with a positive predictive value of 77%. There were 18 false-negatives. Eleven of these false-negatives had an associated hemothorax and 6 had pneumopericardium. A single patient had 2 negative US examinations and returned with delayed cardiac tamponade. CONCLUSIONS: The sensitivity of US to detect hemopericardium in stable patients was only 86.7%. The 2 main factors that limit the screening are the presence of a hemothorax and air in the pericardial sac. A new regimen for screening of occult injuries to make allowance for this is proposed.

Effective induction of melanoma-antigen-specific CD8+ T cells via Vγ9γδT cell expansion by CD56(high+) Interferon-α-induced dendritic cells.

Dendritic cells (DCs) can be differentiated from CD14+ monocytes in the presence of interferon-α (IFNα) and granulocyte/macrophage-colony stimulating factor (GM-CSF) in vitro and are known as IFN-DCs. Circulating blood CD56+ cells expressing high levels of CD14, HLA-DR and CD86 have been shown to spontaneously differentiate into DC-like cells in vitro after their isolation from blood. We show here that IFN-DCs expressing high levels of CD56 (hereafter, CD56(high+) IFN-DCs) can be differentiated in vitro from monocytes obtained as adherent cells from healthy donors and patients with metastatic melanoma. These cells expressed high levels of CD14, HLA-DR and CD86 and possessed many pseudopodia. These CD56(high+) IFN-DCs may be an in vitro counterpart of the circulating CD56+ CD14+ CD86+ HLA-DR+ cells in blood. Conventional mature DCs differentiated from monocytes as adherent cells in the presence of GM-CSF, IL-4 and TNF-α (hereafter, mIL-4DCs) did not express CD56 or CD14. In contrast to mIL-4DCs, the CD56(high+) IFN-DCs exhibited a stronger capacity to stimulate autologous CD56+ Vγ9γδT cells highly producing IFNγ in the presence of zoledronate and IL-2. The CD56(high+) IFN-DCs possessing HLA-A*0201 effectively induced Mart-1-modified melanoma peptide (A27L)-specific CD8+ T cells through preferential expansion of CD56+ Vγ9γδT cells in the presence of A27L, zoledronate and IL-2. Vaccination with CD56(high+) IFN-DCs copulsed with tumor antigens and zoledronate may orchestrate the induction of various CD56+ immune cells possessing high effector functions, resulting in strong immunological responses against tumor cells. This study may be relevant to the design of future clinical trials of CD56(high+) IFN-DCs-based immunotherapies for patients with melanoma.

Adapting a blended motivational interviewing and problem-solving intervention to address risky substance use amongst South Africans.

The purpose of this study was to examine the acceptability and initial substance use outcomes of a blended motivational interviewing (MI) and problem-solving therapy (PST) intervention, delivered by peer counsellors. Twenty people who scored at risk for substance use according to the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) received a five session blended MI-PST intervention and were assessed at baseline and at three months. An open-ended semi-structured interview, designed to identify possible factors that may hinder or promote the acceptability of the intervention was also conducted. Fifteen participants completed the intervention and the three-month follow-up. According to ASSIST scores, participants significantly reduced their substance use (p > 0.001) at the three-month follow-up. Randomized controlled trials are needed to evaluate the effect of this intervention more rigorously.

Time since injury is the major factor in preventing tranexamic acid use in the trauma setting: An observational cohort study from a major trauma centre in a middle-income country.

BACKGROUND: Haemorrhage is responsible for about a third of in-hospital trauma deaths. The CRASH-2 trial demonstrated that early administration of tranexamic acid, ideally within 3 hours, can reduce mortality from trauma-associated bleeding by up to 32%. OBJECTIVE: To explore whether, in our trauma network in a middle-income country, patients arrived at hospital soon enough after injury for tranexamic acid administration to be effective and safe. METHODS: A prospective cohort study of 50 consecutive patients admitted to our trauma unit was undertaken. Inclusion criteria were as for the CRASH-2 study: systolic blood pressure <90 mmHg and/or heart rate >110 beats per minute, with injuries suggestive of a risk of haemorrhage. Patients with isolated head injuries were excluded. The mechanisms of injury, time since injury and any reasons for delay were recorded. RESULTS: Thirteen (26%) patients presented early enough for tranexamic acid administration. Of these, only three patients presented within the 1st hour. Eleven patients had a documented time of injury >3 hours prior to presentation. We were unsure of the time of injury for 26 patients, although for most of these it was likely to be >3 hours before presentation. CONCLUSIONS: The majority (74%) of bleeding trauma patients did not present within the timeframe allowed for safe administration of tranexamic therapy. Of those who did, most would have benefited from even earlier commencement of therapy. This raises the possibility that tranexamic acid may be more effective on a population basis if incorporated into prehospital rather than in-hospital protocols; future studies should explore the benefits and risks of this approach.

Sternotomy or drainage for a hemopericardium after penetrating trauma: a randomized controlled trial.

OBJECTIVE: To determine if stable patients with a hemopericardium detected after penetrating chest trauma can be safely managed with pericardial drainage alone. BACKGROUND: The current international practice is to perform a sternotomy and cardiac repair if a hemopericardium is detected after penetrating chest trauma. The experience in Cape Town, South Africa, on performing a mandatory sternotomy in hemodynamically stable patients was that a sternotomy was unnecessary and the cardiac injury, if present, had sealed. METHODS: A single-center parallel-group randomized controlled study was completed. All hemodynamically stable patients with a hemopericardium confirmed at subxiphoid pericardial window (SPW), and no active bleeding, were randomized. The primary outcome measure was survival to discharge from hospital. Secondary outcomes were complications and postoperative hospital stay. RESULTS: Fifty-five patients were randomized to sternotomy and 56 to pericardial drainage and wash-out only. Fifty-one of the 55 patients (93%) randomized to sternotomy had either no cardiac injury or a tangential injury. There were only 4 patients with penetrating wounds to the endocardium and all had sealed. There was 1 death postoperatively among the 111 patients (0.9%) and this was in the sternotomy group. The mean intensive care unit (ICU) stay for a sternotomy was 2.04 days (range, 0-25 days) compared with 0.25 days (range, 0-2) for the drainage (P < 0.001). The estimated mean difference highlighted a stay of 1.8 days shorter in the ICU for the drainage group (95% CI: 0.8-2.7). Total hospital stay was significantly shorter in the SPW group (P < 0.001; 95% CI: 1.4-3.3). CONCLUSIONS: SPW and drainage is effective and safe in the stable patient with a hemopericardium after penetrating chest trauma, with no increase in mortality and a shorter ICU and hospital stay. (ClinicalTrials.gov Identifier: NCT00823160).

A straight left heart border: a new radiological sign of a hemopericardium.

BACKGROUND: Detection of a cardiac injury in a stable patient after a penetrating chest injury can be difficult. Ultrasound of the pericardial sac may be associated with a false negative result in the presence of a hemothorax. A filling in of the left heart border inferior to the pulmonary artery, called the straight left heart border (SLHB), is a radiological sign on chest X-ray that we have found to be associated with the finding of a hemopericardium at surgery. The aim of the present study was to determine if this was a reliable and reproducible sign. METHODS: This was a prospective study of patients with a penetrating chest injury admitted between 1 October 2001 and 28 February 2009, who had no indication for immediate surgery, and were taken to the operating room for creation of a subxiphoid pericardial window (SPW). The chest X-ray was reviewed by a single trauma surgeon prior to surgery. RESULTS: A total of 162 patients with a possible occult cardiac injury underwent creation of a SPW. Fifty-five of the 162 patients (34 %) were noted to have a SLHB on chest X-ray and a hemopericardium confirmed at SPW. The sensitivity of the SLHB sign was 40 %; specificity, 84 %; and positive predictive value, 89 %. (p = 0.005, Odds ratio 3.48, lower 1.41, upper 8.62). CONCLUSIONS: The straight left heart border is a newly described radiological sign that was highly significant in predicting the presence of a hemopericardium and should alert the clinician to a possible occult cardiac injury.

Emergency pancreatoduodenectomy for complex injuries of the pancreas and duodenum.

BACKGROUND: This single-centre study evaluated the outcome of a pancreatoduodenectomy for Grade 5 injuries of the pancreas and duodenum. METHODS: Prospectively recorded data of patients who underwent a pancreatoduodenectomy for trauma at a Level I Trauma Centre during a 22-year period were analysed. RESULTS: Nineteen (17 men and 2 women, median age 28 years, range 14-53 years) out of 426 patients with pancreatic injuries underwent a pancreatoduodenectomy (gunshot n = 12, blunt trauma n = 6 and stab wound n = 1). Nine patients had associated inferior vena cava (IVC) or portal vein (PV) injuries. Five patients had initial damage control procedures and underwent a definitive operation at a median of 15 h (range 11-92) later. Twelve had a pylorus-preserving pancreatoduodenectomy (PPPD) and 7 a standard Whipple. Three patients with APACHE II scores of 15, 18, 18 died post-operatively of multi-organ failure. All 16 survivors had Dindo-Clavien grade I (n = 1), grade II (n = 7), grade IIIa (n = 2), grade IVa (n = 6) post-operative complications. Factors complicating surgery were shock on admission, number of associated injuries, coagulopathy, hypothermia, gross bowel oedema and traumatic pancreatitis. CONCLUSIONS: A pancreatoduodenectomy is a life-saving procedure in a small cohort of stable patients with non-reconstructable pancreatic head injuries. Damage control before a pancreatoduodenectomy will salvage a proportion of the most severely injured patients who have multiple injuries.

Resection and reconstruction in high-grade pancreatic head injuries.

This study by Chui et al adds further important evidence in the treatment of high-grade pancreatic injuries and endorses the concept of the model of pancreatic trauma care designed to optimize treatment, minimize morbidity and enhance survival in patients with complex pancreatic injuries. Although the authors have demonstrated favorable outcomes based on their limited experience of 5 patients who underwent a pancreaticoduodenectomy (PD), including 2 patients who were "unstable" and did not have damage control surgery (DCS), we would caution against the general recommendations promoting index PD without DCS in "unstable" grade 5 pancreatic head injuries.
